MINING-MACHINE TRUCK.

Application led May 19, 1922, Seria1 No. 562,231. Renewed June 18,`1923.

To all whom it may concern:

Be it known that I, ROY NORMAN, a citizen of the United States, residingat St.y

Louis, in the' county of St. Louis and State of Missouri, have inventedcertain new and useful Improvements in Mining-Machine Trucks, of whichthe following is a full, clear, and exact specification.

My invention relates to mining machine trucks.

It hasfor its object to provide ank improved truck adapted to transporta mining machine and of animproved construction whereby it is possibleto load the mining machine from either end of the truck or to unload themachine from either end ofthe latter thereby materially facilitating theprocess of loading or unloading under certain mining conditions. Afurther object of my invention is to provide an improved truckespecially adapted to use with long Wall machines having thecharacteristics above set forth and provided With improved means wherebythe mining machine may be connected to the truck during loading orunloading with facility, andheld in transport position on the truck.

In the accompanying drawings, Ihave shown for purposes of illustrationone embodiment which my invention may assume in practice. p

In these draWings,-

Fig. l is a plan view of a truck constructed in accordance With myimprovement.

Fig. 2 is a side elevation of the same, the machine being shown in aloaded position in dotted lines.

F ig. 3 is a diagrammatic View showing a mining machine unloading fromeither vend of the truck.

In my improved construction the truck body 1 is preferably provided Withusual guide surfaces 2 at its sides and is also preferably but notnecessarily mounted upon Wheels 3 at points on either side of itstransverse center line, While each end of the truckv is open and adaptedto receive a mining machine. f

The truck body of my improved construction is herein made of uniformtransverse section above its Wheels to provide the usual machinecarrying portion and provided with liared end portions i each alsohaving the usual guiding surfaces forming a continuation of the guidesiirfaces 2. '-Io facilitate they movement of the 4mining machinerelative to these ends, a plate 5 is also preferably disposed over thebottom of each of the flared portions as shown and the end of `thisplate as at 6 is bent slightly downward to form a portion contacting`with the bottom end over which the machine may slide freely up ont()the body of the plater when the end Ofthetruck is depressed asillustrated in Fig. 3.

In order to permit the flexible feeding member of a mining machine to beconnccted to the truck Without obstructing either machine receiving end,I have also herein cut away as at 7 each portion 6 and provided anabutment 8, herein in the form of a'chain fork, in a plate 9 disposedlloeneath the plate 5. In order to enable the machine to be held intransport position upon the truck, I have also provided upstandingmembers 10 at either yside of the truck adjacent the beginning ofeachflared portion thereof and have provided transverse openings ll inthese'upstandingportions adapted to receive one or more rods orfbar's l2which Will thus be vdisposed above the cutter bar of the mining machinevand in front of the machine frame in such a manner as to preventmovement of the latter in one direction relative to the truck.Cooperating with this holding means I have provided one or more pins 13adapted `to be received in corresponding openings 14 in the bottom ofeach flared end and near the extremity thereof, which are adapted toengage with the opposite end of the machine. TO prevent loss vof thesepins, chains l5 herein connect them to the truck. Attention is also'directed to the fact that at each side of each end of thetruck I haveprovided a combined feed member hook and mule haulage connectioncomprising a hook 16 adapted to be engaged bythe flexible feeding memberon the mining machine to permit the latter to move relative to the truckduring unloading and an aperture 17 adapted to permit a mule haulageconnection to be made tothe truck if desired.

As result of my improved `construction it Will be noted that'allnecessity for turning the truck around to receive a mining machine isobviated, the truck being capable of receiving the mining machine yatlfLloaded withfacility irrespective of which end of the truck is used.

' While I have in this application specifically 'described oneembodiment which m invention may assume in practice, it'wil r beunderstood that this form of the same is shown for purposes ofillustration and that the invention kmay be modified and embodied invarious other forms without departing from its spirit or the scope ofthe appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. A mining machine truck comprising a body having provision forreceiving a. mining machine at either end thereof.

2. A mining machine truck comprising a body having provision fordischarging a mining machine at either end thereof.

3. A mining machine truck comprising a body having a flared miningmachine receiving portion at each end thereof.

7 4. A mining machine truck comprising a ybody having a iared miningmachine receiving portion at each end thereof and an intermediateportion of uniform crosssection.

5. The combination with a mining machine truck having provision forreceiving a mining machine at each end thereof, of means for holding amachine in position therein without interfering with said function.

6. The combination with a mining machine truck having provision fordischarging a mining machine at each end thereof, of means for holding amachine in position therein without interfering with said function.

7. A mining machine truck comprising a f truck body lhaving truck wheelssubstantially midway between its lends and provision for receiving amining machine at either end thereof.

8. A mining machine truck comprising a truck body having truck wheelssubstantially midway between its ends and on opposite sides of itstransverse center line and provision for receiving a mining machine ateither end thereof.

9.'A mining machine truck comprising a body portion adapted to receive amining machine at either end thereof and adapted toy pivot about dierentlongitudinally spaced pivots when a load is moved longitudinally overdifferent ends of said portion.

10. A mining machine truck comprising a wheeled body portion adapted toreceive a mining machine at either end thereof and adapted to pivotabout different sets of wheels .when a load is moved longitudinally overdifferent ends of said portion.

11. The combination with a mining inachine truck comprising a truck bodyhaving truck wheels substantially midway between its ends and provisionfor receiving a mining machine at either end thereof, of flexible feedmember abutments for loading or unloading at either end.

12. The combination with a mining machine truck comprising a truck bodyhaving truck wheels substantially midway between its ends and provisionfor receiving a mining machine at either end thereof, of flexible feedmember abutments at either end thereof disposed out of the path of amining machine.

13. The combination with a mining machine truck comprising a truck bodyhaving truck wheels substantially midway between its endsy and provisionfor receiving a mining machine at either end thereof, of loading andunloading flexible feed member abutments at each end thereof, theloading abutments being disposed substantially in the center line of thetruck body out of the path of a mining machine.
